5 1 GENERAL 5 The CDN 117 and CDN 118 coupling - decoupling networks provide a means for injecting standards-compliant surge pulses into signal and datalines, as well as telecom lines. These networks are used in combination with surge generators. Tests can be performed on equipment, assemblies and installations while they are in operation. These tests and their required coupling methods are prescribed in various test standards (e.g. IEC / EN , IEC / EN ). Specifications and recommendations regarding the execution of the tests, and their severity, the permissible reaction by the equipment under test (EUT), etc. can be found in the relevant standards. The CDN 117 with the suffix -M are shipped with a pair of cables that fit Teseq s NSG 3000 family generator or Modula. CDN 118-T4 and CDN 118-EXT-1 are shipped with cables for Teseq s NSG 3000 family generator or Modula. Cables for other generators are available as option. 1.1 Safety The CDN 117 and CDN 118 coupling - decoupling networks are designed for operation with high voltage generators, which contain high energy levels. Incorrect or careless operation can be lethal! The following safety measures must be strictly and responsibly observed at all times. Users must also comply with all safety advice that is provided with generators that are used with the CDN 117 and CDN 118.

6 6 Neither Teseq AG, Luterbach, Switzerland nor its associated sales organizations accept any responsibility for personal injury or for any material or consequential damage resulting from negligent operation of this equipment. These instruments have been designed in conformity with the relevant safety regulations and provide all the necessary requirements for safe and reliable operation. 1.2 Safety measures These operating instructions form an integral part of the equipment and must be carefully studied before putting the equipment into operation and must be available to the user at all times. WARNING - The equipment must only be used by trained personnel. Personnel fitted with a heart pacemaker must neither operate the equipment nor remain in the test vicinity when the generator is in operation. These instruments are not designed for use in an explosive atmosphere. The test equipment is to be set up in conformity with the relevant safety standards (e.g. VDE 104). The coupling network housing must be properly grounded (earthed). To ensure safe operation, only approved accessories, plugs, adapters, etc. are to be used. The setup must offer insulation protection against voltage which is at least equal to the pulse voltage. The pulse voltage must not be able to find its way to ungrounded metallic objects even if the EUT is faulty or fails. CDN 117 / 117-M CDN 118 / 118-M Signal & data line coupling networks

7 Depending on the type of EUT and especially on its cabling, a considerable amount of interference can be radiated which could affect nearby systems and radio communication. These environmental interference effects to be controlled by the user through the use of suitable measures such as a Faraday cage, shielded cable runs, etc Installation Since the CDN 117 and CDN 118 do not have their own power supplies, they have not been assigned a protection class. However, they are typically operated according to protection class 1 in view of their electrical connection to pulse generators and the metallic parts of their casing. Local installation regulations must be respected to ensure the safe flow of leakage currents. WARNING - Operation without a ground (protective earth) connection is forbidden! Operate the equipment only in dry surroundings. Any condensation that occurs must be allowed to evaporate before putting the equipment into operation. Do not exceed the permissible ambient temperature, humidity or altitude. Ensure that a reliable return path for the interference current is provided between the EUT and the generator. The reference ground plane and the ground connections to the instruments that are described in the relevant test standard will serve this purpose well. These instruments should be opened only by a qualified specialist if specifically instructed to do so in the operating manual.

8 8 1.4 Test execution The test area must be organized so that no unauthorized persons have access during execution of a test. If a safety contact (interlock) is used as a means of access control to the test area (e.g. Faraday cage), then an additional contact in series with any hazardous voltages or currents is necessary to provide protection for parts of the EUT that are in danger of being touched. EUTs, together with their accessories and cables, are to be considered live during a test. The test generator must be stopped and the EUT supply interrupted before any work can be performed on the EUT. This can often be achieved by opening the interlock circuit, depending on the type of generator in use. The EUT is to be tested only in a protective cage or under a hood which provides protection against electric shock and all manner of other dangers pertaining to the particular EUT. The safety instructions for all instruments and associated equipment in the test setup are to be observed. The configuration of the test setup is to be strictly in compliance with the methods described in the relevant standard to ensure that the test is executed in a compliant manner. Note: Please use a NSG 3000 series generator with Ed.2 Surge module in combination with a CDN 117 / 118 for IEC :Ed.2 testing and a NSG 3000 series generator with Ed.3 Surge module in combination with a CDN 117 / 118 for IEC :Ed.3 testing.

9 2 FUNCTIONAL DESCRIPTION 9 The CDN 117 and CDN 118 coupling - decoupling networks, together with their accessories, provide a means to inject standardized surge pulses into signal, data and / or telecom lines. These coupling networks can be used in situations where the inputs and outputs of mains-free connection lines must be tested for interference immunity. The CDN 117 and 118 are designed to be used in conjunction with a surge pulse generator. They enable tests to be performed on equipment or systems while they are in operation, by eliminating the attenuation of the surge pulse by auxiliary equipment (AE). The AE must usually be protected by surge suppressors against the effects of excessively high residual currents. Relevant tests and coupling methods are described in the test standards IEC / EN , IEC / EN , IEC / EN , etc. 2.1 CDN 117 The versatile CDN 117 can be used on either unscreened (or unshielded), unsymmetrically driven signal lines as well as on unscreened signal and data lines. The network enables symmetric (line to line) and asymmetric (line to ground) coupling of 1.2 / 50 µs hybrid pulses into pairs of conductors. The test pulse is inductively decoupled from the input side of the CDN (AE terminals) so that the surge pulse is coupled as fully as possible to the EUT via the output terminals. The integral 40 Ω series resistors raise the source impedance of the pulse generator to 40 Ω. (Since the 2 Ω output impedance of the generator is a complex quantity, the combined value of the generator plus 40 Ω lies closer to the required value of 40 Ω).

10 10 Several CDN 117s can be arranged in parallel for applications where more than two conductors must be decoupled. A special coupling cable is needed. DC decoupling must be achieved with a coupler type INA 170 or INA 174A. The coupling mode can be changed by relocating the connecting cable from the pulse generator. 1.6 AT 20 mh A 40 Ω A in PE PE out B 1.6 AT 20 mh 40 Ω B Functional schematic of the CDN 117 INA 170 The INA 170 contains a coupling spark gap without a capacitor. The spark gap has a trigger voltage of 90 V. INA 174A The INA 174A contains a 0.5 µf capacitor that can be connected in series with the 40 Ω already incorporated in the coupling network. This type of coupling element is used for capacitive injection into unscreened signal and data lines. CDN 117 / 117-M CDN 118 / 118-M Signal & data line coupling networks

11 2.2 CDN 118 This device is used on unscreened or unshielded, symmetrically driven telecommunication lines. 11 The network enables symmetric (line to line) and asymmetrical (line to ground) coupling of 1.2 / 50 and 10 / 700 µs pulses into pairs of conductors. The test pulse is inductively decoupled from the input side of the CDN (AE terminals) so that surge pulse is coupled as fully as possible to the EUT. A high value decoupling choke is required due to the large voltage-time characteristic of the 10 / 700 µs pulse. The requisite series resistors are arranged in separate boxes so that all required modes can be achieved by proper connection of the INA 370 cable. DC decoupling can be performed by using either the INA 170 coupling device. L1 L1 in L2 A L2 out PE B PE L3 L3 C L4 L4 D Functional schematic of the CDN 118

12 12 3 TEST SETUPS Each test setup should be carefully planned. All the equipment should be securely positioned, and all cables should be securely connected. The safety advice given in Sections 1 and 2 and in the generator manual must be observed. The EUT and the wiring should be handled only when the generator is not active. Various test setups and test methods are possible. The following sections provide examples with more precise details. 3.1 Connections There are two black safety laboratory sockets on the top left of the CDN 117. Both lines (L1 and L2) are marked as input and each is protected by a 1.6 A fuse. These input sockets share a common ground point which is internally and permanently connected to the housing of the coupling network. The signal or data lines from auxiliary equipment or loads, such as sensors, detectors, converters, temperature probes, switching elements, etc., are connected to these line inputs. The output (out), to which the EUT must be connected, is positioned on the right hand side. The EUT could be, a computer, any type of signal amplifier, an evaluation device or a general type of central system controller. The common ground socket is connected to the housing. The pulse connections from the generator are plugged into two of the five high voltage sockets to obtain the required type of coupling.
